media_device_init — Initializes a media device element
void media_device_init ( | struct media_device * mdev); |
This function initializes the media device prior to its registration. The media device initialization and registration is split in two functions to avoid race conditions and make the media device available to user-space before the media graph has been completed.
So drivers need to first initialize the media device, register any entity
within the media device, create pad to pad links and then finally register
the media device by calling media_device_register as a final step.
